Recommends and Supplements are the same - just from a different angle

pkg a recommends b
  is the same as
pkg b supplements a

the only difference is in the 'pattern' itself where we have so-called
'hardware supplements' - which are handled by inr --no-recommends (as per 
man page, hardware supplements and languages are handled specifically)

install-new-recommends (inr) [options]
Install newly added packages recommended by already installed ones. This
command basically re-evaluates the recommendations of all installed packages
and fills up the system accordingly. You don���������t want to call this
unconditionally on small or minimal systems, as it may easily add a large
number of packages.

Called as zypper inr --no-recommends, it restricts the command to just look for
packages supporting available hardware, languages or filesystems. Usefull after
having added e.g. new hardware or driver repos. This is also the default
behavior if you have set [zypp.conf:solver.onlyRequires].
